To (LZZ whom, it may concern:

Be it known that I, JOHN B. M. V. RoTTIN- GER, a citizen of the UnitedStates, and a resident of the borough of Manhattan, city of New York, inthe county of New York and State of New York, have invented certain newand useful Improvements in Machines for Removing and Cutting Materialfrom Cores, of which the following is a specification.

This invention relates to means for removing paper or other materialfrom cores, spindles, and the like and cutting the same into sheets. Itsorganization consists of a machine for removing paper or other materialfrom cores, and among its essential elements are adjustable supports forthe said cores and a reel adjacent thereto for winding the paper orother material thereon. A knife is connected up with the reel forcutting the said paper or other material.

In the drawings, Figure 1 represents a front elevation of the inventionwith partial sections of Fig. 2 as on the lines m as and 00 as. Fig. 2is an end view of Fig. 1 with a partial section on the line 20 x Figs. 3and 4 show plan views of portions of Fig. 1.

The invention comprises framing with the stationary upright A andupright B, which latter is adjustable between the guides C and along thegirders D, a bolt D, with washers D clamping the upright B and girders Dtogether. On the upright A are mounted the journal-bearings E E E E E,with the bolts e. On the upright B are mounted the journal-bearings F FF F F, with the bolts The journal-bearings E, &c., carry spindles G,each of which has mounted on one end thereof a tapering spring-supportcomprising the springs G, which are clamped to the spindles G by meansof the collars G the ends 9 of the springs being generally bent over theend of the spindle G. Collars H are fastened to the spindles G by meansof screws h. In the journal-bearings F, &c., are mounted similarspindles J, generally somewhat longer than the spindles G, and whicheach have a tapering spring-support, consisting of the springs J,secured on the spindles J by means of the collars J the ends 7' of thesprings J being generally bent over the end of the spindle. Collars Kare secured on the spindles J by means of screws To the rear of theframe with the uprights A and B are secured uprights L, L, and L the twolatter of which carry journal-bearings M and M by means of bolts m m".In the said bearings M M is supported an axle N, which carries a reelcomprising the ends 0 and longitudinal members O. The ends O areconnected to the flanged supports O which in turn are fastened to thesaid axle I.

Supports P are fastened to the axle N and to which are journaled thelevers P on the pivots The levers P are connected by the link P and theother ends of the levers P are connected to the knife-support Q, towhich latter is fastened the knife R by means of the screws 1". Thecutting edge 1" of the knife may be curved, as shown or straight. 7

To one of the levers P is pivoted a link S, which latter is connectedwith a lever T, that is pivoted to a support T, the latter being carriedon the axle N. The lever T contains a socket for an operating-handle T,which can be removed. Stops T are adjustably fastened to the axle N tocontrol the movements of the lever T.

On the left-hand side of the axle N is supported the shaft V,with thepulley V and disk V the j ournal-bearing M being fastened to the uprightL. On the end of the axle N is carried the disk W,With the centralprojection W and grooved collar W, a eather W extending from the axle Nand fitting the said grooved collar W and disk W. A lever Y, with itsforked end Y fitting the groove of the collar W is pivoted on a bracket1, extending from the upright L. A shaft 2 is supported in bearings 3,and on the latter shaft is fastened the roller 4, which is located toengage with the projection W of the disk W. Asecond roller 5, connectedwith a sleeve 6 and grooved collar 7, is arranged to slide on the shaft2, a feather 8 being interposed between the shaft 2 and the roller 5with its sleeve 6. A lever 9 is pivoted to a bracket 10, that extendsfrom the upright L, and the forked end 11 of the lever 9 is engaged bythe grooved collar 7. I

To the rear of the frame carrying the sprin supports and under the reelare secured rails 12 for the wheels 13 of a truck 14. Sides 15 arehinged from the body of the truck, which sides can be pulled up and theends thereof connected by a chain and the like to prevent the materialcarried thereon from falling off.

To use the invention, cores like Z Z are each placed on a pair of thespring-supports, the spindles J being moved to the right by looseningthe collars 7c to allow the cores to be put in place on the springs G onleft-hand side of the frame, after which the spindles J with the springsJ, are pushed up into the cores and the collars 76 again fastened. Thesprings will tightly grip the cores in place. Although only two cores,each with a roll of paper thereon, are shown in the drawings, it isevident that a core may be placed on all of the pairs of supports. Theends of the rolls of paper are then placed and wound around the reel,which latter is then caused to turn by moving the lever Y so that theprojection W of the disk W engages with the roller 4. The roller 5 isdriven by the disk V and the speed of said roller 5 can be varied bymoving the same on the shaft 2 by means of the forked lever 9, becausedifferent speeds are given to the roller 5 when it is engaged with thedisk V at different distances from the axis of the shaft V. When it isdesired to stop the reel turning, the diskW, with its proj ectignw, isbrought out of engagement with the roller l'. After a sufficient numberof thicknesses of paper have been wound around the reel the knife R ismade to cut the same by operating the handle T the depth of the cut ofthe knife being controlled by the stops T on the axle N. After the paperhas been cut the sheets are allowed to fall on the truck 14, when thehinged sides 15 are swung up and connected by a chain, so as to preventthe paper falling off of the said truck.
